Up until now, I found The Curse to be engaging, sometimes unpredictable and at best above average. This episode changed that for me. Here, we see the continued deterioration of Whitney and Archers dichotomy of emotions fully erupt. His ability to be so petulantly passive aggressive and then erupt violently was great. It felt organic and deserved. The interplay between Whitney and the buyers was also spot on in feeling real and not the usual writer's imagination of what real life is like. There was a real world vibe to it.
I see where the resolution is coming from for the end of the series but it doesn't matter. Getting there has just picked up speed.
